Concord grapes are one of the most popular and widely cultivated grape varieties in the United States. Known for their dark purple color, juicy flavor, and versatility in both wine production and fresh consumption, Concord grapes have become a staple in many American households. But have you ever wondered if these delicious grapes can be grown in North Carolina? In this article, we’ll delve into the world of Concord grapes and explore the possibility of growing them in the Tar Heel State.
Understanding Concord Grapes
Before we dive into the specifics of growing Concord grapes in North Carolina, it’s essential to understand the characteristics of this grape variety. Concord grapes are a type of Vitis labrusca, a species of grape native to North America. They were developed in the 19th century by Ephraim Wales Bull, a Massachusetts farmer who sought to create a grape that was both disease-resistant and suitable for the cold New England climate.
Concord grapes are known for their:
- Dark purple color
- Large, round clusters
- Sweet, juicy flavor
- Thick skin
- High acidity
These characteristics make Concord grapes an excellent choice for wine production, juice, and fresh consumption.
Climatic Requirements for Growing Concord Grapes
Concord grapes are relatively adaptable to different climates, but they do require specific conditions to thrive. They prefer:
- Cool winters: Concord grapes need a certain amount of chill hours (hours below 45°F) to break dormancy and produce fruit.
- Warm summers: They require warm temperatures during the growing season to ripen the fruit.
- Well-drained soil: Concord grapes prefer soil with good drainage and a pH between 5.5 and 6.5.
North Carolina’s climate is generally suitable for growing Concord grapes, with the western part of the state being more conducive to grape cultivation due to its cooler winters and warmer summers.
Can Concord Grapes Grow in North Carolina?

Do Concord Grapes Grow in North Carolina?
Concord grapes can be grown in North Carolina, but they are not as widely cultivated as other grape varieties in the state. This is due to the fact that Concord grapes are more commonly associated with cooler climates, such as those found in the Northeastern United States. However, with proper care and attention, it is possible to grow Concord grapes in North Carolina’s temperate climate.
In order to successfully grow Concord grapes in North Carolina, it is essential to choose a location with well-draining soil and full sun. The vines should also be regularly pruned to promote healthy growth and fruit production. Additionally, growers may need to take steps to protect their vines from extreme heat and humidity, which can be challenging in North Carolina’s climate.
What is the Best Climate for Growing Concord Grapes?
Concord grapes are typically grown in cooler climates with moderate temperatures and well-defined seasons. They thrive in areas with warm summers and cold winters, which allows them to go dormant during the winter months. The ideal temperature range for growing Concord grapes is between 35°F and 85°F (2°C and 30°C), with average annual temperatures ranging from 40°F to 60°F (4°C to 15°C).
In terms of specific climate zones, Concord grapes are often grown in USDA Hardiness Zones 4-8. These zones provide the necessary chill hours for the vines to go dormant during the winter, which is essential for fruit production. Growers in warmer climates, such as North Carolina, may need to take extra steps to provide their vines with the necessary chill hours.
Can Concord Grapes be Grown in Containers?
Yes, Concord grapes can be grown in containers, but it requires careful planning and attention to detail. Container-grown grapes need a large enough pot to accommodate the vine’s root system, which can grow quite extensive. A minimum pot size of 12-18 inches deep and 24-36 inches wide is recommended.
When growing Concord grapes in containers, it is essential to provide the vines with a trellis or other support system to help them grow upright. The soil should also be well-draining and fertile, with regular fertilization to promote healthy growth. Additionally, container-grown grapes may require more frequent watering, as the soil can dry out quickly in hot weather.
How Long Does it Take for Concord Grapes to Mature?
Concord grapes typically take 2-3 years to mature after planting, depending on factors such as climate, soil quality, and pruning practices. During the first year, the vines will focus on developing their root system and growing vegetatively. In the second year, the vines will start to produce flowers and fruit, but the yield may be limited.
It is not until the third year that Concord grape vines typically reach their full production potential. With proper care and attention, a mature Concord grape vine can produce up to 20-30 pounds of fruit per year. However, the exact yield will depend on factors such as climate, soil quality, and pruning practices.
Are Concord Grapes Susceptible to Any Pests or Diseases?
Yes, Concord grapes are susceptible to several pests and diseases, including powdery mildew, black rot, and spider mites. Powdery mildew is a fungal disease that can cause a white, powdery coating to form on the leaves and fruit. Black rot is a fungal disease that can cause the fruit to turn black and rot. Spider mites are tiny, spider-like insects that can cause yellowing or bronzing of the leaves.
To manage these pests and diseases, growers can use a combination of cultural, chemical, and biological controls. Cultural controls include practices such as pruning, sanitation, and irrigation management. Chemical controls include the use of fungicides and insecticides. Biological controls include the use of beneficial insects and microorganisms to control pest populations.
Can Concord Grapes be Used for Wine Production?
Yes, Concord grapes can be used for wine production, but they are not typically used for high-end wines. Concord grapes are often used for juice production, jam-making, and other culinary purposes. However, they can be used to produce a sweet, fruity wine that is similar to a rosé.
When using Concord grapes for wine production, it is essential to follow proper winemaking techniques to ensure the best possible flavor and quality. This includes steps such as cold soak, fermentation, and aging. The resulting wine will be a sweet, fruity wine with a distinctive flavor profile.
Where Can I Buy Concord Grape Vines in North Carolina?
Concord grape vines can be purchased from a variety of sources in North Carolina, including nurseries, garden centers, and online retailers. Some popular options include the North Carolina State University Cooperative Extension, which offers a variety of grapevine cultivars, including Concord.
When purchasing Concord grape vines, it is essential to choose a reputable supplier to ensure that the vines are healthy and disease-free. Growers should also choose a vine that is well-suited to their specific climate and soil conditions. Additionally, it is a good idea to consult with a local expert or gardening professional to get advice on the best way to plant and care for the vines.
